Thorax Phantom

For testing the influence of scan parameters in CT



The Thorax Phantom is used as (semi-)anthropomorphic surrounding for multiple image quality inserts. It comprises artificial lung lopes, a spine insert, and a shell of soft tissue-equivalent material.

The plastics used mimic human tissues with respect to density and X-ray attenuation characteristics of a human thorax.

There are multiple standard cylinders (D100) for image quality purposes available (see options section).
